RESILIENT SHOE-HEEL SECTION OR LIFT.

I eas es.-

Application filed May 15, 1916.

To all whom it may concern:

Be it known that I, GEORGE H. LEWIS, a citizen of the United States, residing at- Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Resilient Shoe-Heel Sections or Lifts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to sections or What are more commonly'known as lifts for shoe heels, the object of my invention being to provide a resilient lift for shoe heels which will adhere, throughout 'its use, closely to the leather or wooden sections of the shoe heel, without the use of cement or other ad.- hesive material. The shoe heels which have hitherto been in use, so far as I amaware, have been made flat or concave-convex in one form or another. The flat heels are open to the objection that in use a seam soon opens up between the resilient lift and the portion of the shoe to which it is attached, which, in addition to forming an. ugly opening. admits dirt and water ,between the resilient lift and the other portion of the shoe, which, as can be readily understood, will be objectionable for a good many reasons. I am aware that efforts have been made to fastening the flat heel to the leather or wooden section of the heel by the use of cement. This, however, causes considerable delay in applying the rubberlift to the shoe, in addition to increasing the work of the shoe-maker. In fact, it makes it impracticable for people to apply the lifts to their own shoes.

I aim to produce a lift which can be applied very quickly to the shoe by the shoe maker, or which can be conveniently applied by any one to shoes, and which will always adhere closely throughout its whole surface, and especially at the edges of the shoe heel.

Another object of my invention is the provision of a heel lift which can be more conveniently and cheaply made than the concave-convex heel lift, and

form as nearly as practicable the same func and at the same time the nails become loosened, the center and away from leather section of the heel.

tions as said heel lift will not, in case draw in toward the edge of the Specification of Letters Patent.

overcome this objection by which will per-- Patented Apr. 31?, JLQIW. Serial No. 97,575.

By tightly fastening, through the use of screws or nails, those portions of the edges of the lift 'not automatically maintained in close contact with the surface to which the lift is attached, I overcome certain objections to those types of rubber heel lifts not i so curved as to close all parts of the margins of the interengaging surfaces of the lifts and heels, and at the same time produce a lift which can be cheaply and con veniently made.

Other objects of my invention and the invention itself will probably be better understood from a. description of an embodiment of the invention.

Figure 1 is a side elevation of an embodiment of my invention.

Fig. 2 is a top plan view of the same.

Fig. 3 is a front elevation of the same.

Fig. 4 is a section through the line H of Fig. 2.

Fig. 5 is a section through the line 55 of Fig. 2

Fig. 6 is a section through the line 6-6 of Fig. 2.

Fig. 7 is an elevation of the lift applied to a shoe heel.

Fig. 8 is a front elevation of a second embodiment of my invention.

Fig. 9 is a plan elevation of the embodiment shown in Fig. 8.

Referringnow to the drawing, and first to the embodiment of my invention shown in Figs. 1 to 7 inclusive, first portion or wing of the heel and at 11 the second portion or wing which is positioned at an-angle to the first portion or wing 10. These parts meet at any suitable line. The distance 13*14 may be about one-third the distance l213. The line 1415 where the parts join is substantially a straight line perpendicular to the long axis of the heel lift. The angle at which the portions join on the top of the heel is sharp, but on the bottom it is preferably slightly curved at 16, so that there will be no ridge at this place when the heel is flattened out, as shown in Fig. 7. The upper and lower surfaces of the portions 10 and 11 are both substantially flat. The surfaces 20 and 21 thus form a dihedral angle, shown As will be seen, the lift possesses considerable thickness and is made of rubber or some other resilient material. When] fiattened, as shown in Fig. 7, the two portions at 10 is shown the 10 and 11 tend, with considerable force, to reassume the position shown in Fig. 1, cansing the upper surface of the lift to adhere very closely to the bottom of the heel sec tion to which the lift has been applied. This force, of course, will be most strongly felt at the front edge 12 and through the periphery of the rear edge 18. The force will be sufiicient all along the edge to prevent a seam opening up between the lift and the section of the heel to which it is applied and also to prevent any water or dirt leaking in. If any dirt or water should leak in, due to the heel being improperly attached, the pressure will tend to expel the same. It will be seen that this heel may be attached without the use of cement. It

can simply be nailed on by any person in a short time.

The lift is fastened to the shoe by any suitable means, such as nails or screws 51. Openings 40, 41 and 42 are provided for these nails or screws, such openings extending part way through the lift, as shown in Figs. {1- and 6. A Washer is provided around each opening for the head of the nail or screw to rest upon. The fastening means should be applied adjacent the apex of the dihedral angle, so as to better flatten out the lift when in use. I also prefer to attach fastening means in each portion or wing of the lift.

In the embodiment shown in Fig. 8, the portions 30 and 31 are longitudinal, the surfaces 32 and 33 being longitudinal and the dihedral angle 34 between these portions is parallel to the longitudinal axis of the heel. The operation will be the same as in the form shown in Figs. 1 to 7 inclusive.

I have illustrated these embodiments for the purpose of explaining my invention and showing that the dihedral angle may extend in any suitable direction with respect to the long axis of the heel. Moreover, I contemplate numerous and extensive departures from the form and details illustrated without departing from the spirit of the invention.

I claim l. A resilient shoe heel lift consisting of a plurality of portions, each portion having an upper plane surface, said portions and surfaces being normally at an angle to each other.

2. in a resilient heel lift, the combination of a plurality of portions normally forming a dihedral angle.

3. As an article of manufacture, a re silient heellift normally having an obtuse dihedral angle in its upper surface.

4. In a resilient heel lift, the combination. of a pair portions each having an upper and a lower plane surface, the upper surfaces being normally at an angle to each having an obtuse, dihedral angle the line of,

whose apex is in the upper surface of the lift and substantially perpendicular to the long axis of the lift.

6. In a resilient heel lift, the combination of a plurality of portions, each having an upper and a lower plane surface substanstantially equi-distant apart, the upper and lower surface of each of the portions being substantially parallel to each other, the upper and lower surface of said portions forming dihedral angles, the dihedral angle in the upper surface being sharp and the apex of the dihedral angle in the lower surface being curved.

7. In a resilient heel lift, the combination of a plurality of portions, each having an upper and a lower plane surface substanstantially equi-distant apart, the upper and lower surface of each of the portions being substantially parallel to each other, the upper and lower surface of said portions forming dihedral angles, the dihedral angle in the upper surface being sharp and the apex of the dihedral angle in the lower surface being curved, the lines forming the apices of said dihedral angles being substantizglly perpendicular to the long axis of the li t.

8. In a resilient heel lift, the combination of a plurality of united wings constituting the body of the lift inclined to each other, and means for fastening the lift to the heel applied adjacent the part where the wings unite.

9. In a resilient heel lift, the combination of a plurality of wings inclined to each other to form an obtuse dihedral angle, and means for connecting said lift to a shoe ap plied adjacent the apex of said angle.

10. In a resilient heel lift, the combination of a plurality of Wings inclined to form a dihedral angle, fastening means applied adjacent the apex of said angle to connect said heel to the shoe and other means to connect eachof the wings to the shoe.

11. In a resilient heel lift, the combination of a plurality of wings, and means to connect said lift to a shoe, one of said wings being normally inclined to said attaching means.
